A

An insert inside the face piece of a SCBA that fits over the users mouth and nose

29
Q

Occupational Safety and Health Administration (OSHA)

A

The US federal agency that regulates worker safety and in some cases, responder safety. It is part of the US Department Labor

30
Q

Open Circuit Breathing Circuit

A

SCBA in which the exhaled air is released into the atmosphere and is not re-used

31
Q

Oxygen Deficieny

A

Any atmosphere where the oxygen level is less that 19.5 %. Low oxygen levels can have serious effects on people, including adverse reactions such as poor judgement and lack of muscle control

32
Q

PBI

A

A fire retardant synthetic material used in construction of personal protective equipment

33
Q

Personal Alert Safety System (PASS)

A

A device that continually monitors for the lack of movement of the wearer and if no movement is detected, automatically activates an alarm signal indicating the wearer is in need of assistance. The device can also be manually activated to trigger the alarm system

34
Q

Personal Protective Equipment (PPE)

A

The basic protective equipment for wild land fire suppression include a helmet, protective footwear, gloves and flame resistant clothing as define by NFPA 1977

35
Q

Phosgene

A

A chemical agent that causes severe pulmonary damage; it is a byproduct of incomplete combustion

36
Q

Pounds per square inch (PSI)

A

The standard unit for measuring pressure

37
Q

Pressure gauge

A

A device that measures and displays pressure readings. In an SCBA, the pressure gauges indicate the quantity of breathing air that is available at any time

38
Q

Protective hood

A

A part of fire fighter’s personal protective equipment that is designed to be worn over the head and under the helmet; it provides thermal protection for the neck and ears

39
Q

Rapid Intervention crew/ Company universal air connection (RIC UAC)

A

A system that allows emergency replenishment of breathing air to the SCBA of disable or entrapped fire or emergency services personnel (NFPA 1981)

40
Q

Respirator

A

A device that provides respiratory protection for the wearer (NFPA 1994)

41
Q

SCBA harness

A

The part of SCBA that allows fire fighter to wear it as a “backpack.”

42
Q

SCBA regulator

A

The part of the SCBA that reduces the high pressure in the cylinder to a useable lower pressure and controls the flow of ai to the user

43
Q

Self contained breathing apparatus (SBCA)

A

A respirator with an independent air supply that is used by fire fighters to enter toxic or otherwise dangerous atmosphere

44
Q

Self contained underwater breathing apparatus (SCUBA)

A

A respirator with an independent air supply that is used by underwater divers

45
Q

Smoke Particles

A

Airborne solid materials consistent of ash unturned or partially burned fuel released by fire

46
Q

Supplied air respirator (SAR)

A

An atmosphere supplying respirator for which the source of breathing air is not designed to be carried by the user (NFPA 1404)

47
Q

Two way radio

A

A portable communication device used by firefighters . Every fire fighters should carry at least one radio to communicate distress, progress, changes in fire conditions, and other pertinent information

48
Q

What kind of protection is provided by PPE?

A
  1. Provides thermal protection
  2. Repels water
  3. Provides impact protection
  4. Protects against cuts and abrasions
  5. Furnishes padding against injury
  6. Provides respiratory protection
49
Q

List the three layers of turnout gear and their function

A
  1. Outer Layer or shell is constructed of sturdy, flame resistant, water repellent material such as Nomex, Kevlar or PBI
  2. Second layer is the moisture layer which usually consist of a flexible membrane attached to thermal barrier material. It helps prevents the transfer of water, steam and other fluids to the skin
  3. Third Layer compromises a thermal barrier, which is multilayered or quilted that insulates the body from external temperatures. To enables the FF to operate in elevated temperatures generated by fire and keeps the body warm during the cold months 1st
50
Q

When operating on a roadway what piece of PPE must you have and what is the standard?

A

A bright colored reflective safety vest. It must meet ANSI standard 207. This standard requires the vest contain 450 sq inches (11 meters) of high visibility fabric and 201 sq inches (5 meters) of retro-reflective material.

51
Q

What are some of the downsides to FF’s PPE?

A
  1. Its heavy at nearly 50 lbs of extra weight
  2. It retains body heat and perspiration therefore the body cannot cool itself
  3. Limits mobility
  4. Decrease sensory abilities
  5. It reduces peripheral vision
  6. Speaking becomes muffled so harder to communicate
  7. Decreased hand dexterity
52
Q

What kind of clothing should you avoid under turnout gear and why? Which articles of clothing as safe?

A

Nylon or Polyester should be avoided due to them melting. Cotton and Wool are safer to wear due to them charring without melting. Nomex and PBI are the safest and can withstand high temperatures

53
Q

Smoke includes what three components:

A

Particles
Vapors
Gases

54
Q

What happens when oil based compounds burn?

A

They produce small hydrocarbon droplets that become apart of smoke

55
Q

What is the danger associated with Carbon Monoxide?

A

It is deadly even in small quantities. It is odorless, tasteless, and colorless. When inhaled in it quickly replaces oxygen in the bloodstream and it binds with the hemoglobin 200x times more readily than oxygen.

56
Q

What is the by-product when plastic products are burned?

A

Hydrogen Cyanide. It is quickly absorbed by blood stream and interfere with cellular respiration.
